Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679540, here are decompositions:

11 + 8679529 = 8679540
13 + 8679527 = 8679540
41 + 8679499 = 8679540
83 + 8679457 = 8679540
113 + 8679427 = 8679540
167 + 8679373 = 8679540
193 + 8679347 = 8679540
229 + 8679311 = 8679540

Showing the first eight; more decompositions exist.
